JOSEPH W. WA'ITLES, OF CANTON, MASSACHUSETTS.

Letters Patent No. 98,133, dated December 21, 1869.

The Schedule referred to in these Letters Patent and making part of the same.

To all persons to whom these presents may come:

Be it known that I, JOSEPH W. IVATTLES, of Canton, of the county of Norfolk, andState of Massachusetts, have made a new and useful invention, having reference to the lubrication of holsters and stcps'of the spindles of spinning-machines; and I do hereby declare the same to be fully described in the following specification, and represented in the accompanying drawing, which represents a vertical section of a spindle, and its bolster and step, as provided with my invention.

In carrying out my invention, I extend from the bolster down by the whirl,'and to the step, aconduit or tube, so applied to the bolster and step as to convey oil from the interior bearing of the bolster, or an intercep'ting chamber, a, formed therein, down into the step, the whole being as hereinafter explained.

In the drawings- A denotes a spindle, B the bolster, and C the step,

the whirl'being shown at E.

The conduit or pipe leading from the bolster to the step is shown at D, it being made to open out of an int-ercepting chamber, a, formed in the bolster and around the spindle. l

' At its foot, the tube opens into the spindle-step, which is' also provided with an oil-chamber.

The top of the bolster is concave, to receive the. oil.

The surplus oil of the bolster will 'flow down through the tube, and into the step. In case the bolster be provided with the interccpting chamber, such oil will tirst be caught thereby.

My improvement renders it necessary to apply oil to the bolster only, and saves the necessity of applying it also to the step. waste oil from runnin down from the bolster and upon the spindle and whirl. It eii'ects a very considerable saving oi' oil, over what would be required'for the separate lubrication of the bolster and step in the ordinary way.

In order 'that the conduit may be readily applied to and removed from the step and bolster, to facilitate the removal either of the latter from their supportingrails, I provide the step, as well as the bolster, with a It prevents much if not ,all

hole or passage, leading laterally out of it, such' being as shown at b and o, for the reception of the end of the conduit, such conduit being applied to the step and bolster by being sprung into said holes or pass: ges.

From the above it will be seen, that by .the arrangement of the tube or conduit D, it bows around the whirl, so as not to interfere with it, the said whirl being sitated between the step and the bolster.

I am aware of the lubricator of Lesfe, the specification and drawings of which were tiled in the Patent Office on December 9, 1865, and, consequently, make no claim to such. It is somewliataualogous to my in-y vention, though very different therefrom, both in con-- struction and mode of operation. It applies toa single tubular bearing of a shaft. I ts tube is not arranged as'mine is, viz, so as to bow around the whirl or drivi'ngpulley, and lead from one bearing, over such whirl,

to a separate and distinct step arranged below it.- 1t. simply has an oil-chamber at the top of the bearing', with no part of the bearing extended above such oilchamber, as is the case with my bolster'.

l The bearing of Lesfe is continuous to the step, and* opens communication therewith, so that oil may tlow upward from the step, through vthe endless bearing, and into the intercepting chamber, and thence out of such through its discharge-tube; but with my bolster and step, no such action of the oil can take place.

What I claim, tnereforc, as my invention in spinning-machines, is-

. The arrangement of the conduit D, relatively tothe bolster, the whirl, and the step of the spindle, the bolster being above and the step-being below the whirl,
